SPECIFICATION forming part of Letters Patent No. 566,478, dated August 25, 1896.

Application filed August '7, 1895. Serial No. 558A58. (No model.)

To all whom, it may concern.-

Be it known that I, BENJAMIN S. SEAMAN, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Bicycle-Saddles, of which the following is a full, clear, and eXact description, reference being had to .the accompanying drawings, making part of this specification.

My invention relates to improvements in bicycle-saddles; and it-consists of certain features of construction and combination of parts, as will be hereinafter described and claimed.

Figure 1 of the drawings is a plan view of a piece of sheet metal from which the saddleframe blank is pressed or out. Fig. 2 is a similar view of the saddle-frame blank. Fig. 3 is a perspective of the saddle-frame. Fig. i is a similar view of the adjustable pommelframe. Fig. 5 is a similar View of the seatadjusting screw. Fig. 6 is a similar view of the threaded nut. Fig. 7 is a similar view of the cantle-frame from rear under side. Fig. Sis a longitudinal section through the frame. Fig. 9 is a perspective of the front end of the frame. Fig. 10 is a similar view showing the frame in cross-section as secured to the post. Fig. 11 is a cross-section of frame as from as to m, Fig. 3. Fig. 12 is a perspective of saddle-piece. Fig. 13 is a longitudinal vertical sectional view of the complete saddle; and Fig. 14 is a cross-section on line y 1 Fig. 13.

A denotes the cantle-frame, and B the support, which are of the form shown in Fig. 3 and are made of a single piece of sheet metal of desired thickness.

The process of construction consists, first, of punching or otherwise cutting out from a sheet of metal, as C, (shown in Fig. 1,) a blank, as D. (Shown in Fig. 2.) About the cantle portion of the blank are provided apertures a,by which the seat-leather is secured thereto. The blank D cut from the sheet metal is stamped or pressed into the form shown in Fig. 3, having the outer edges Z) of the cantle flanged downwardly, as shown in Figs. 3, 7 and 8, the middle part curved to conform to the seat-leather, and the laterally and forwardly projected lobes E and the U-shaped support B formed by the downwardly-flanged sides of the before-mentioned blank D, thus forming a continuously-flanged edge about the cantle and support, for the purposeof making said parts rigid and strong, the forward end portion of which is by another op eration formed into a cylinder portion 0, as shown in Fig. 9, adapted to receive the seattightening screw F, and at the end portion of the support are provided recesses d, adapted to receive the dowels e on the nut G, by which the nut is secured to the support and against rotation.

The screw F is placed in the cylinder por tion 0 of the support B, the nut G resting on the end thereof, the dowels e in the recesses (1, over which is placed the pommel-support H, which is formed substantially as shown in Fig. 4., having downwardly and rearwardly projected arms h, which are adapted to be secured to the seat-leather, a transverse portion j, in which is provided an aperture is, adapted to receive and support the front end Z of the screw F, and a forwardly and downwardly projected portion m, adapted to support the front or pommel portion of the seatleather. The rear ends of the sides h are connected by the cross-rod h, which extends across the support B, and which not only prevents the sides spreading, but also prevents the saddle-leather coming in contact with the support B and injuring the rider.

To adjust the frame hereinbefore described to the seat-leather, the screw F is turned into or out of the nut G, by which the pommelframe H is moved forward or back on the frame 13.

To further strengthen the support B, a re inforcing-plate J is provided, stamped to conform to the under side of the support B and the front central portion of the cantle A, as shown in Figs. 7, 8, 10, and 11.

To secure the support 13 to the post K, a saddle-piece, as L, is provided having side grooves 19 to receive and support the lower edges of the support B when secured to the post K by the clamp M.

The object attained by the hereinbefore described structure is a bicycle-saddle frame of greater rigidity and strength, of less weight, and at a greatly-reduced initial cost.

Having thus fully described the nature and object of my invention, what I claim is- A bicycle-saddle frame stamped from a single piece of sheet metal and comprising the cantle-fraine having the marginal depending perforated portion of lobes E from which project asupport B semicircular or U-shaped in cross-section for a portion of its length and circular in cross-section for the remaining portion of its length and provided with the notches din combination with a strengthening-plate semicircular in cross-section for a portion of its length and having one of its ends flattened, the said semicircular portion of the strengthening-plate being arranged within and secured to the semicircular portion of the support and the flattened portion of the plate being permanently secured to the body of the frame, a saddle-leather attached to the depending perforated portion with one end, a pommel-frame attached to the front end of the saddle-leather and straddling the support 13 and provided with an underlying cross-bar b to sustain the weight when the saddle-leather is depressed, a nut G having cars which engage the notches in the support 13, and a screw F, one end of which projects into the support B and the other end of which has a swivel connection with the pommel substantially as set forth.

In testimony whereof I have hereunto set my hand this 2d day of August, A. D. 1895.

BENJAMIN S. SEAMAN.
